Sustainable Sources was founded in 1994 by Bill Christensen as a means to spread information about green building and related fields in an efficient, inexpensive way over the then-new world wide web.

Our many years of work on the internet can be a tremendous advantage to you – we routinely clean up confusing and slow loading sites, provide fundamental knowledge about making your site “search engine worthy”, and provide site owners and webmasters with tips and tricks to enhance your site.
